Crawling the web
The

website links contain the links of the other web pages creating a path for
crawlers to reach pages on the website.
Whenever
the crawlers visit a web page, they go through the document object model to see
what is on the page whether it is an image, video, and content. The DOM goes
through the HTML structure to see how internal links are placed. This is how
the search engine finds new pages on the web.
In
addition, crawling the entire page in a day is not possible as mentioned
earlier crawlers can take weeks to crawl a website.

terms, indexing is the collection of databases, and web pages crawled by the
search engine bots. The index of organizes and catalogs:

·
Map down the links of the website
·
The clickable text of any link

their location on the page, and other aspects.

index work as a database for Google so, when a query pops up, it searches and
finds out the suitable from the index to satisfy the query of the user. Right
before the search engine select which page to show from the database or index
